1/ 0 (ZZZ whom it may concern:

Be it known that I, JAY C. PIERSOL, a citizen of the United States, residing at Hinton, in the county of Plymouth and State ofIowa, have invented certain new and useful Improvements in a Haystacker; andIdo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide a relatively simple and readily portable, or transportable stacker adapted for movement to and from the field or location of the proposed stack and adapted to be readily set up for operation under conditions providing for a gradual building of the stack to any desired height under circumstances in which the existence of a wind will not interfere with the work, and with the minimum of eifortand loss of time upon the part of the operator and at the same time with the minimum of power so far as the team is concerned, and with these general objects in view the invention consists in a construction,

combination and relation of parts of which a. typical embodiment is illustrated in the accompanying drawings, wherein:

Figures 1 and 2 are respectively plan and side views in the transport position of a stacker embodying the invention;

Fi ure 3 is a side view at the completion of the first and the beginning of the second step in the erection of the stacker for operation;

the end of the first step in the operation of erecting the frame to hold the base against movement on the surface of the ground during the hauling of the frame to the upright position;

Figure 9 is a detail view of the front end supporting draft truck used in transporting the mechanism from place to place.

The machine consists essentially of a normally or operatively upright frame 10 of generally arched form having a base consisting of a transverse beam 11 and side transport wheels 12 which are mounted upon spindles arranged at a sufficient distance from the base bar, or forwardly thereof when the frame is in a horizontal position, to entirely clear said base bar and therefore come in contact with the ground surface only when the frame is in a horizontal or transport position indicated in Figures 1 and 2, a front end supporting draft truck 13 having wheels 14 and a draft pole or its equivalent 15 and adapted to uphold the front or normally upper end of the frame when in the transport or substantially horizontal position, a suitable connection being provided between the frame and the truck to permit of readily detaching the latter, and consisting in the construction illustrated of a king bolt 15 for engaging a suitable bearing 16 in the truck, and a carrier 17 which is mounted for movement longitudinally of the frame, or vertically thereon when in the upright position shown in F igures 3, 1, and 5, together with suitable; operating mechanism for the control and elevation of the carrier.

Pivotally mounted as at 18 on the side braces or uprights of the frame, in suitable clips 19, are the front and rear braces 20 and 21 adapted for diagonal bracing positionforwardly and rearwardly of the frame to maintain it in a fixed upright position during the operation of the stacker, said braces preferably being anchored when in the proper position as by means of pins 22 driven through suitable openings in the heels or lower ends of the brackets, the pivotal mounting of these braces adapting them to be folded into parallelism with the frame I when the latter is in the transport position.

To prevent spreading of the braces when in operative position limiting or retaining chains 23 are employed extending from the lower portions of the side members of the frame to the lower ends of the braces and fitted with adjusting means such as the bolts 23 for tensioning the same to bring the frame to an upright position before pinning the lower ends of the braces to the ground.

Assuming that the mechanism is in the transport position indicated in Figures 1 and 2, the tilting thereof toward the upright or operative position is effected upon the axles of the rear transport wheel as a fulcrum or axis, thereby disengaging the upper or front end of the frame from the supporting draft truck, and when this tilting movement has been effected sufficiently to bring the edge of the base bar into contact with the ground it is preferable to anchor the latter as by driving stakes 24 into the eyes or rings 25 of anchor lockers 26 mounted upon the base bar at its lower front corner, so that in the further elevation of the frame it may pivot on said rockers as an axis. Connected with the frame at its rear side and at an intermediate level is an elevating cable 27 of looped form, to which a team may be attached to raise the frame to the upright position. When this elevation of the frame is about to occur it is preferred to release the ends of the front braces which are extended forwardly in the transport position of the mechanism so that they may drag upon the ground and serve as a stop to hold the frame in a partly elevated position should the draft upon the elevating cable be discontinued.

As the frame approaches the upright position these front braces obviously will drag on the ground until they reach a proper position for anchoring. During the same operation the rear braces should be held in an outward or rearwardly swung position so that they may be properly located to check the rearward swinging movement of the frame when it reaches the upright position. The adjusting and anchoring of the frame may be then eflected.

Secured to the upright frame 10 at the outer sides thereof, as by bolts 18*, and to the base beam 11, as by brackets 19 are brace members 2O which in addition to their bracing functions form means to support one end of each of the bearing shafts 21 of the transporting wheels 12 and also means of attachment for the clips 19, constituting fastening means for the upper ends of the braces 20 and 21. The heads of the bolts 18 are countersunk in the guides 34 in order that they will not form obstruct-ions and thereby interfere with the free sliding movement of the slides 33 on the guides.

The illustrated form of carrier comprises essentially a receiving or carrying fork 30 and a discharging or delivery fork 31 having parallel axes of movement preferably consisting of a common transverse member 32 of which the ends are attached to slides 33 mounted for movement upon guides 34 at the inner sides of the uprights of the frame to facilitate the elevation and lowering of the carrier in the operation of forming a stack. Rigidly attached to the receiving fork in an oblique or inclined relation with the plane thereof is a yoke 35 to which is loosely connected a pulley block 36 around which extends a loop of the operating or elevating cable 37, one end of which is shown attached to the cross bar or arch of the frame and the other portion of which extends around a directionv pulley 38 at the crown of the arch, another pulley 39 at one side of the arch and a further pulley 40 at the foot of the frame, a suitable draft mechanism or animal and preferably a team being attachable to said cable for raising the carrier to the desired elevation. Obviously the first effect of applying a strain or tension to the operating cable is to draw the obliquely disposed yoke into a plane approximating the vertical so as to raise the free ends of the tines of the receiving fork and thus prevent the hay or other material which has been deposited upon said fork by means of a drag rake or any equivalent means from dropping from the same and at the same time tending to shift the load rearwardly or toward the plane of the delivery fork. In its normal position the delivery fork which as above indicated is mounted for pivotal movement upon the common rod forming the axis of the receiving fork, is inclined forward substantially in contact with the lifting yoke of the receiving fork, and it is preferable to provide means for locking the delivery fork in this position so that it may be retained in such relation to the re ceiving fork as to prevent premature dis charge of the load which has been deposited upon the latter, and to this end a latch -11 having actuating spring 412 is mounted upon the delivery fork in position to engage one of the series of teeth 43 on a catch bar 4st carried by the yoke, and flexibly connected as by means of a chain or cord -15 with the latch, and if desired supported by an auxiliary spring s7, is a weight 48 in the form of a weight box which may be loaded with stones or any available objects to a degree sufficient to insure the disengagement of the latch from the catch when the carrier reaches the desired elevation. In practice it is desirable to raise the carrier only a distance necessary to insure the proper deposit of the load upon the spot selected for the stack and to successively increase the path of upward movement of the carrier as the height of the stack increases, so that the material may be deposited upon the stack under such conditions as not to expose it to the influence of wind which would tend to seatter the same, and by varying the length of the flexible connection between the latch and the weight, or in other words by adjusting the length of said connection, it is obvious that the disengagement of the latch and therefore the release of the delivery fork to permit of the swinging movement thereof to the delivery position shown in full lines in Figure 5 may be set to occur at any desired elevation, beginning at only a slight elevation above the ground when the stack is started and being gradually increased as the stack is increased in height.

limited by the length or vertical proportions of the guide frame which by reason of the fact that it can be arranged horizonally for transport purposes may be made of practically any height desired by the operator without involving any serious inconveniences in manipulation and 'transporation.

The delivery fork is yieldingly held in its normal or load retaining position preferably by springs 50 or the equivalent there of and therefore when the latch is disengaged to release the same, it is moved to its discharging position by the weight of the load and the latch operating weight as the latter is lifted from the ground as indicated in Figure 5, and the delivery fork is thus held in the downwardly and rearwardly inclined discharging position until the load has entirely left the same, whereupon the slacking of the draft or operating cable by backing the team to permit of the weight coming into contact with the ground will result in the prompt return of the delivery fork by its actuating springs to the normal or closed position where it will be locked by the reengagement of the latch with the catch. 'VVhen the mechanism is to be arranged for transportation the carrier is swung rearwardly through the frame and is advanced to the normally upper or forward end thereof so that the ends of the tines of the receiving forks rest upon the arch of the fram and leave the under side of the frame unobstructed for the operation of the supporting and draft truck. On the other hand when the frame is about to be erected to the upright position the carrier is preferably moved rearwardly or downwardly to the bottom of the frame so that it is not necessary to raise the weight thereof in bringing the frame to its normal or upright position, and as the frame assumes the upright position the carrier will then swing forward to the receiving position which is indicated in Figure 4 with the extremities of the tines of the receiving fork in contact with the surface of the ground.

As a means of stiffening the foldable frame to permit of constructing the same of a relatively light weight, it is preferred to provide the side members thereof with truss braces 50 having turn buckles 51 so that the tension rods may be tightened as required to preserve the. proper stiffness.

Furthermore, in order to permit of a Obviously the height to which a stack may be built is only certain degree of flexibility in the mounting of the carrier, so that any irregularities in the operation of the hoisting cable tending to cause the movement of one of the slides 33 in advance of the other, it is preferred to construct the transverse member 32 upon which the carrier is fulcrumed in the form of a tubular rock shaft 32 with its terminals revolubly mounted upon fulcrum pins or spindles 32) secured to the slides. The pins or spindles may be of slightly less diameter than the bore of the shaft so as to allow for a degree of looseness which will permit of an angular disposition of the rock shaft under the conditions above indicated without causing cramping or amming of the parts in the elevation or lowering of the carrier, while the displacement of the parts is prevented by reason of the extension of the pins or spindles to a considerable length into'the bore of the shaft.
